I am currently using Critter Creek Lab in
Lincoln, CA. There web site has info on the tests they do.
Mostly I use the green house screening, but with plants whose look
disagrees with the result, or the loss is too painful, I have the plant retested
with their 4 well test. One false negative (a plant with color break in
the flowers) was cleared up with the further test, and a plant with no symptoms
at all still came up positive on the more elaborate test. I think one
should avoid any sample material that is desiccated or more than 2 years
old.
